HARDWARE

Houses will tend to settle over time so that the operation of locks, tilt handles, sash balances and hinges must be checked regularly. All must operate properly for security and fire safety. Door hinges are provided with an adjustment feature so that doors may be adjusted even after some movement. Hinged doors are made to the highest quality specifications but any heavy blinds or accessories mounted on the panels will void the warranty unless previously approved by IWC.

Hardware must be regularly cleaned, lubricated and maintained. In some areas with windborne sand or salt air rollers and hardware must be cleaned every six months or sooner.

ROLLERS

Keeping your patio door and window tracks free of dirt and debris will prevent the rollers from binding and will reduce excessive wear. Use silicone spray if you want to lubricate your window rollers or tracks. Do not use any oil-based lubricants as they may cause metal
rollers to collect dirt and nylon rollers to deteriorate. Properly adjust your patio door rollers to align the lock and keeper (strike plate) and to ensure a smoother operation.

You can adjust your patio door rollers by inserting a Phillips screwdriver through the hole located at the lower end of each door vent panel and at all four corners of your screen door.
